TEXT LINES SHOULD NOT APPEAR WITHIN A FUNCTION
A function is not able to produce text lines like a macro can. TFORM
returns this message if it finds any text entered into the FUNCTION
construct; you can only enter certain commands (see the description of
FUNCTION in Section 3).
THE FIELD AND PAGENUMBER CHARS MUST DIFFER
The title field separator character (default “|”) and the page number
character (default “#”) must be different. A DEFINE command has
attempted to make one the same as the other.
THIS COMMAND OR FUNCTION NAME ALREADY EXISTS
TFORM discovered that a FUNCTION command or a MARCO command
referred previously existing function or macro.
THIS COMMAND SHOULD NOT APPEAR WITHIN A FUNCTION
You may only use these commands in a FUNCTION construct: ASSIGN,
ERROR, and COMMENT commands and those in the IF and LOOP
constructs.
THIS FUNCTION IS NOT DEFINED
You tried to invoke a function that does not exist. You might check the
spelling in your command line.
